Quantum error correction and fault tolerance seek to protect fragile quantum information against noise, enabling reliable quantum computation on imperfect hardware. Our research develops new quantum error-correcting codes, architectures and theoretical principles for scalable fault-tolerant quantum computation. We work on quantum LDPC codes, topological and bosonic quantum codes, decoding algorithms, and the co-design of quantum hardware and software, with the goal of identifying resource-efficient routes towards large-scale quantum computers.
